Hinge construction



NOV. 12; 1935. G, HU E HINGE CONSTRUCTION Filed June 18, 1934 Patented Nov. 12, 1935 UNITED STATES PATENT OFFICE 1 Claim.

My invention relates to improvements in hinge construction for a stove or range door.

The principal object of the device is to provide a, concealed hinge construction which permits of the door being opened Another object of the invention is to provide a concealed hinge construction which does not necessitate unduly weakening the door frame.

Other and further objects of the invention will be apparent when the following specification is considered with the accompanying drawing, in which:

Figure 1 is a front elevation of a stove door and frame embodying my invention;

Figure 2 is a transverse section taken on the line 2-2 of Figure 1;

Figure 3 is a horizontal section taken on the line 3-3 of Figure 1;

Figure 4 is a fragmentary bottom plan view of one corner of the door and frame, showing the door in open position; and Figure 5 is-a fragmentary rear view of the door and frame, showing the door in open position, part of the door frame being in section to disclose a modified form of hinge pin.

Referring more particularly to the drawing 2 designates a preferably cast door frame, the door opening 3 of which is to be closed by means of.

a door 4. This frame has its top and bottom rails 5 and 6, and one side rail 1, inwardly formed with the door seating portions 8, the other side rail 9 being recessed to provide a vertically disposed channel IO, somewhat circular in cross section. This channel permits of free swinging movement of the door 4 mounted to swing with its rear or hinged edge or end portion ll within the channel. The top'and bottom rails 5 and 6 of the frame are provided with forwardly extended lugs I2 and [3, respectively, arranged in alignment with the channel l0 and cooperating with covered ear portions 14,15 at the upper and lower rear ends of the door 4 in supporting same. Perforations [6, in the lugs l2 and I3, and perforations I! in the ear portions l4 and I5, permit of a hinge connection to be made between the 'door and frame by means of split hinge pins [9. The axial centers of the perforations l6 are aligned with the front edge of the top and bottom rails and the axial centers of the perforations H in the ear portions l4 and I5 are aligned with the front face I8 of the door 4, to permit of the door being freely rotated through an arc of 180 degrees, see Figure 4.

The hinge pins l9, extend through the perforations l6 and H in the lugs and ears, and their split ends project into curved recesses '20, formed in the inner or rear face of oppositely disposed and forwardly projecting bosses 2|, also formed on the hinged end ll of the door. These recesses 20 receive, and the bosses 2|, in which the recesses are formed fully cover and shield the ears I4 and [5. The front faces of the bosses 2! are rounded and thus are adapted to guide the upper and lower front end of the door in the vertically disposed rounded channel I0, when the door is opened. 7

When it is desired to assemble the door, the door is inserted into position so that the sealing flange 22 thereof rests upon the door seating portions 8. In this position the perforations l8 and Il are aligned and the split hinge pins H) can readily be inserted, and after the door has been opened, the pins can be spread, as shown in Figure 2. It will also be seen, that by hinging the door in the manner described, the door can readily be opened 180 degrees. The hinge arrangement is completely covered; thus eliminating objectionable sharp edges and extensions on the door and frame.

It is obvious that instead of the split pins, used to hingedly connect the door and frame, drive pins 23 such as illustrated in Figure 5, may be employed. The roughened or ribbed portion 24 of these pins is forcibly driven into the lugs l3 and I4 and securely interlocked therewith, whereas the smooth ends 25 serve as pivots about which the ears I5 and I6 freely rotate during swinging movements of the door with respect to the frame.

It will be noted that the, use of my concealed or covered hinge construction, which is particularly adapted for ranges, stoves and furnaces, permits of the outer surface of the door being substantially flush with the outer surface of the frame, thus enhancing the appearance of the stove or furnace as well as providing a hinge of simple, inexpensive construction.

Having thus described my invention,

What I claim is:

In a hinge construction for range doors or similar devices, a door frame having a recessed marginal portion at one side thereof, upper and lower lugs extending outwardly from said frame in alignment with said recessed marginal portion and having pin receiving apertures, a door having upper and lower ears arranged partly beyond the outer face and partly beyond the inner face of the door, and pins passing through the lugs and ears in alignment with the main portion of the door, whereby the door may swing in an arc. of 180 degrees.
